Be sure to keep up with Jagex's Rules while on Runescape, and obey AL's rules here on the forums. Before attending to a war, we reiterate that reading Warring 101 will greatly increase your experience in-battle.

Also, notice your CAP count. This is your Clan Award Point count, and the more effort you put on improving the clan, the more you earn! You can click it to get more information on it.
